Chinese Patent Application No. 201910816948.7, filed with the China National Intellectual Property Administration on August 30, 2019 - This application relates to the field of electronic device technologies, and in particular, to a fingerprint apparatus, an electronic device, and a manufacturing method thereof.
- With development of science and technology, an electronic device has been basically popularized in all aspects of people's living environment. To make it more convenient for the electronic device to serve people, information exchange between the electronic device and people is crucial. An electronic device such as a mobile phone is used as an example. Information exchange between the mobile phone and a human mainly includes keyboard pressing, screen touching, wireless communication, voice input, facial recognition, fingerprint recognition, and the like. Fingerprint recognition has been widely used in operations such as unlocking and payment in the mobile phone for uniqueness and convenience.
- The mobile phone is used as an example. An existing fingerprint recognition system is usually disposed at a position at which a front physical button is located, disposed on a back, and disposed below a display screen. Nowadays, full-screen display is an important development direction and a technical selling point for future electronic devices such as a mobile phone, and an in-screen fingerprint recognition technology corresponding to full-screen display can draw more attention for user-friendliness. Currently, common in-screen fingerprint recognition technologies include an optical fingerprint recognition technology, a capacitive fingerprint recognition technology, an ultrasonic fingerprint recognition technology, and the like. To improve competitiveness of electronic devices such as the mobile phone, impact of a fingerprint apparatus on architecture design of the electronic devices such as the mobile phone needs to be minimized, and more attention needs to be paid on impact of a location of the fingerprint apparatus in the electronic device and a thickness and an area of the fingerprint apparatus on the architecture design. An existing fingerprint apparatus cannot receive a fingerprint image at a relatively long distance, and therefore usually needs to be installed through attachment to a screen. It is relatively difficult to implement installation through attachment to the screen, and there is a problem that the display screen is scrapped due to poor attachment.
- Embodiments of this application provide a fingerprint apparatus, an electronic device, and a manufacturing method thereof. An installation position is flexible, and therefore a problem that a screen is scrapped due to installation of the fingerprint apparatus through attachment to the screen can be avoided.
- To achieve the foregoing objective, the following technical solutions are used in the embodiments of this application.
- According to a first aspect, an embodiment of this application provides a fingerprint apparatus, including a fingerprint image sensor and a collimator located on a side of the fingerprint image sensor. A first microlens group is disposed on a side of the collimator that is away from the fingerprint image sensor. The first microlens group includes at least one first microlens unit. The first microlens unit is disposed corresponding to a collimator hole of the collimator. The first microlens unit is configured to converge light on the side of the collimator that is away from the fingerprint image sensor to the collimator hole of the collimator.
- The fingerprint apparatus provided in this embodiment of this application includes the fingerprint image sensor configured to receive fingerprint information and the collimator located on the side of the fingerprint image sensor. The first microlens group is disposed on the side of the collimator that is away from the fingerprint image sensor. The first microlens group includes at least one first microlens unit. The first microlens unit is disposed corresponding to the collimator hole of the collimator. The first microlens unit may converge the light on the side of the collimator that is away from the fingerprint image sensor to the collimator hole of the collimator. In this way, when the fingerprint apparatus is relatively far away from a display screen, fingerprint image light information can still be smoothly transmitted to the fingerprint image sensor, thereby removing a limitation that the fingerprint apparatus can be installed only through attachment to the screen. In addition, the fingerprint apparatus may be installed at another position without being attached to the screen. An installation position is flexible, and therefore a problem that the screen is scrapped due to installation of the fingerprint apparatus through attachment to the screen can be avoided.
- With reference to the first aspect, in a first optional implementation of the first aspect, a second microlens group is further disposed between the collimator and the fingerprint image sensor. The second microlens group includes at least one second microlens unit. The second microlens unit is disposed corresponding to the collimator hole of the collimator. The second microlens unit is configured to converge light that passes through the collimator hole of the collimator to the fingerprint image sensor. The first microlens group may converge light that cannot be incident into the collimator hole or that cannot be transmitted in a straight line to the collimator hole, thereby increasing light transmittance. To implement better transmission and imaging of light emitted from the collimator hole, the second microlens group may be further disposed on the other side of the collimator hole. The second microlens group may converge the light that passes through the collimator hole to the fingerprint image sensor, thereby improving a fingerprint recognition effect.
- With reference to the first aspect and the first optional implementation of the first aspect, in a second optional implementation of the first aspect, there are a plurality of first microlens units, the collimator includes a plurality of collimator holes, and the plurality of first microlens units are disposed in a one-to-one correspondence with the plurality of collimator holes of the collimator.

To increase light transmittance of each collimator hole, there may be a plurality of first microlens units, and the plurality of first microlens units are disposed in a one-to-one correspondence with the collimator holes.
- With reference to the second optional implementation of the first aspect, in a third optional implementation of the first aspect, there are a plurality of second microlens units, the collimator includes a plurality of collimator holes, and the plurality of second microlens units are disposed in a one-to-one correspondence with the plurality of collimator holes of the collimator.

- The electronic device provided in this embodiment of this application includes the display screen. The fingerprint apparatus according to any one of the foregoing technical solutions is disposed at an interval below the display screen, and therefore the fingerprint apparatus is not attached to the display screen. In this way, a problem that the screen is scrapped due to installation of the fingerprint apparatus through attachment to the screen can be avoided.
- With reference to the second aspect, in a first optional implementation of the second aspect, a gap between the display screen and the fingerprint apparatus is greater than or equal to 0.1 mm.

FIG. 1 is a schematic stacking diagram of a typical architecture of an existing electronic device such as a mobile phone. The architecture includes ascreen 01 and afastening frame 02. Space below thefastening frame 02 may be divided into abattery region 03 and anon-battery region 04 based on different disposed parts. Thebattery region 03 is used to accommodate a power supply. Thenon-battery region 04 is used to accommodate other optional electronic elements such as a circuit board, a speaker box, a motor, and a camera. Based on the architecture, a fingerprint apparatus is placed below thescreen 01. The fingerprint apparatus may be fastened to thescreen 01 or thefastening frame 02. In addition, the fingerprint apparatus may be located above thebattery region 03 or thenon-battery region 04. Due to a limitation of a structure or the prior art, in the foregoing solution of positions for disposing the fingerprint apparatus, there is a possibility that the fingerprint apparatus cannot be disposed at some of the positions, or there may be some problems after implementation. For example, when the fingerprint apparatus is attached to thescreen 01 for assembly, there is a problem of relatively high costs due to poor attachment, and a limited thickness of the fingerprint apparatus affects a battery capacity or results in an increase in a thickness of the entire device. When the fingerprint apparatus is relatively thick, the fingerprint apparatus can be disposed only above thenon-battery region 04. However, a requirement for a large-area in-screen fingerprint cannot be met due to a limited area of thenon-battery region 04. In a thickness direction of the electronic device, a direction from the fastening frame to the screen is an upward direction, and a direction from the screen to the fastening frame is a downward direction. The fingerprint apparatus may be located above thebattery region 03. It may be understood that the fingerprint apparatus is located above the battery region in the thickness direction of the electronic device, and an orthographic projection of the fingerprint apparatus on the fastening frame is located in a region of an orthographic projection of the battery region on the fastening frame. Correspondingly, the fingerprint apparatus may be located above thenon-battery region 04. It may be understood that the fingerprint apparatus is located above the non-battery region in the thickness direction of the electronic device, and an orthographic projection of the fingerprint apparatus on the fastening frame is located in a region of an orthographic projection of the battery region on the fastening frame. - For example, there are usually the following two implementations for an in-screen fingerprint in the prior art:
FIG. 2 shows an internal structure of afirst fingerprint apparatus 05 in the prior art. Thefingerprint apparatus 05 is installed below ascreen 01, and includes animage sensor 051 and acollimation component 052. When a human finger presses thescreen 01, fingerprint information light of the finger passes through thescreen 01, is integrated by thecollimation component 052, and then is transmitted to theimage sensor 051. Theimage sensor 051 may recognize fingerprint information.FIG. 3 is a schematic structural diagram in which thefingerprint apparatus 05 in this solution is installed in an electronic device architecture. Only thecollimation component 052 with a relatively small size is disposed in thefingerprint apparatus 05 in this solution to fit with theimage sensor 051, and therefore thefingerprint apparatus 05 is relatively thin, and may be installed in abattery region 03 or anon-battery region 04. However, in a solution of attaching thefingerprint apparatus 05 to thescreen 01, there is a problem that thescreen 01 is scrapped due to poor attachment. In addition, if thecollimation component 052 of thefingerprint apparatus 05 in this solution is relatively far away from thescreen 01, there is relatively low light transmittance, an optical fingerprint image is distorted, and recognition cannot be performed well. Consequently, fingerprint information cannot be normally collected, and normal operation is affected. -
FIG. 4 shows an internal structure of asecond fingerprint apparatus 05 in the prior art. Thefingerprint apparatus 05 is installed below ascreen 01, and includes animage sensor 051 and alens structure 053 located between theimage sensor 051 and thescreen 01. When a human finger presses thescreen 01, fingerprint information light of the finger passes through thescreen 01, is focused by thelens structure 053 for reverse imaging, and then is transmitted to theimage sensor 051. Theimage sensor 051 may recognize fingerprint information.FIG. 5 is a schematic structural diagram in which thefingerprint apparatus 05 in this solution is installed in an electronic device architecture. Thelens structure 053 is disposed in thefingerprint apparatus 05 in this solution to fit with theimage sensor 051, and therefore a specific distance is required for optical path propagation of thefingerprint apparatus 05 to ensure reverse imaging, that is, thefingerprint apparatus 05 is relatively thick. Therefore thefingerprint apparatus 05 can be installed only in anon-battery region 04. - An embodiment of this application provides a
fingerprint apparatus 100. Referring toFIG. 6 , thefingerprint apparatus 100 is disposed below adisplay screen 200 of an electronic device, and includes afingerprint image sensor 101, and further includes acollimator 102 disposed between thefingerprint image sensor 101 and thedisplay screen 200. Afirst microlens group 103 is disposed between thecollimator 102 and thedisplay screen 200. Thefirst microlens group 103 includes at least onefirst microlens unit 1031. Thefirst microlens unit 1031 corresponds to acollimator hole 1021 of thecollimator 102, and is disposed above thecollimator 102. Thefirst microlens unit 1031 is configured to converge fingerprint image light information above thedisplay screen 200 to thecollimator hole 1021 of thecollimator 102. - In the
fingerprint apparatus 100 provided in this embodiment of this application, referring toFIG. 6 , thefirst microlens group 103 is disposed on a side of thecollimator 102 that is away from thefingerprint image sensor 101, thefirst microlens group 103 includes at least onefirst microlens unit 1031, and thefirst microlens unit 1031 is disposed corresponding to thecollimator hole 1021 of thecollimator 102. In this way, when thefingerprint apparatus 100 is relatively far away from thedisplay screen 200, the fingerprint image light information can still be smoothly transmitted to thefingerprint image sensor 101, thereby removing a limitation that thefingerprint apparatus 100 can be installed only through attachment to the screen. In addition, thefingerprint apparatus 100 may be installed at another position without being attached to the screen. An installation position is flexible, and therefore a problem that the screen is scrapped due to installation of the fingerprint apparatus through attachment to the screen can be avoided. In addition, a microlens structure with a relatively small size is used to integrate light, which is different from a reflection imaging solution of a convex lens with a relatively large size of a camera in the solution shown inFIG. 4 . Therefore, theentire fingerprint apparatus 100 is relatively thin, and may be flexibly installed at a plurality of positions in small space. - It should be noted that the collimator (collimator) may be made of a material such as a silicon material, glass fiber, or plastic. The collimator is disposed on a surface on a side of the fingerprint sensor, and may be used to block incident light at an angle, to a surface of the fingerprint sensor, that exceeds a specific angle threshold, to ensure that incident light perpendicular to or approximately perpendicular to the surface of the fingerprint sensor is incident on the surface of the fingerprint sensor, so as to improve light utilization and reduce interference from stray light.
- To clearly describe an effect of the
fingerprint apparatus 100 provided in this embodiment of this application, referring toFIG. 7 , when a finger presses thedisplay screen 200, fingerprint light information is transmitted downward through thecollimator hole 1021. A structure of thecollimator hole 1021 disposed on thecollimator 102 is shown inFIG. 8 . For example, further referring toFIG. 7 , the fingerprint light information includes light a and light b in the figure. Thefirst microlens unit 1031 is disposed for acollimator hole 1021 to which the light a points, and nofirst microlens unit 1031 is disposed for acollimator hole 1021 to which the light b points. In this case, the light a is transmitted more efficiently than the light b. Specifically, referring toFIG. 9 , when nofirst microlens unit 1031 is disposed above thecollimator hole 1021, in four beams of light e, f, g, and h shown in the figure, light in a range of f and g can be smoothly transmitted from one side of thecollimator hole 1021 to the other side, and light outside the range of f and g, for example, the light e and h, cannot be correctly transmitted from one side of thecollimator hole 1021 to the other side. In comparison withFIG. 9 , referring toFIG. 10 , when thefirst microlens unit 1031 is disposed corresponding to thecollimator hole 1021, light (including light f and g) in a range of light e and h is refracted and integrated by thefirst microlens unit 1031, and can be smoothly transmitted from one side of thecollimator hole 1021 to the other side. It may be clearly learned that in comparison with a fingerprint apparatus in which nofirst microlens unit 1031 is disposed, in thefingerprint apparatus 100 in which thefirst microlens unit 1031 is disposed, light transmittance is clearly improved. Therefore, when thefingerprint apparatus 100 provided in this embodiment of this application is relatively far away from thedisplay screen 200, thefingerprint apparatus 100 can still normally recognize fingerprint information, and may not need to be attached to thedisplay screen 200 for installation in this case. An installation position is flexible, and therefore a problem that the screen is scrapped due to installation of the fingerprint apparatus through attachment to the screen can be avoided. - To implement better transmission and imaging of light emitted from the
collimator hole 1021, asecond microlens group 104 may be further disposed between thecollimator hole 1021 and thefingerprint image sensor 101. As shown inFIG. 11 , thesecond microlens group 104 includes at least onesecond microlens unit 1041. Thesecond microlens unit 1041 is disposed corresponding to thecollimator hole 1021 of thecollimator 102. Thesecond microlens unit 1041 is configured to converge light that passes through thecollimator hole 1021 of thecollimator 102 to thefingerprint image sensor 101. Thefirst microlens group 103 may converge light that cannot be incident into thecollimator hole 1021 or that cannot be transmitted in a straight line into thecollimator hole 1021, thereby increasing light transmittance. Thesecond microlens group 104 may converge the light that passes through thecollimator hole 1021 to thefingerprint image sensor 101, thereby improving a fingerprint recognition effect. - Referring to
FIG. 8 , thecollimator 102 includes a plurality of collimator holes 1021. To increase light transmittance of eachcollimator hole 1021, there may be a plurality offirst microlens units 1031. Specifically, as shown inFIG. 6 , there are a plurality offirst microlens units 1031, and the plurality offirst microlens units 1031 are disposed in a one-to-one correspondence with the plurality ofcollimator holes 1021 of thecollimator 102. - Similarly, to further converge fingerprint image light information that passes through each
collimator hole 1021 to the fingerprint image sensor, there may be a plurality ofsecond microlens units 1041. As shown inFIG. 11 , there are a plurality ofsecond microlens units 1041, and the plurality ofsecond microlens units 1041 are disposed in a one-to-one correspondence with the plurality ofcollimator holes 1021 of thecollimator 102. - The
first microlens unit 1031 may be a convex lens with a light convergence function, and a specific shape and structure of the convex lens may be flexibly adjusted based on an actual optical path requirement and an assembly requirement. For example, as shown inFIG. 6 , a side, of the convex lens, that faces the collimator hole is relatively flat to facilitate assembly. - Similarly, the
second microlens unit 1041 is a convex lens. Thesecond microlens unit 1041 may be a convex lens with a light convergence function, and a specific shape and structure of the convex lens may be flexibly adjusted based on an actual optical path requirement and an assembly requirement. For example, as shown inFIG. 11 , a side, of the convex lens, that faces the collimator hole is relatively flat to facilitate assembly. - It should be noted that referring to
FIG. 12 , the convex lenses, namely, thefirst microlens unit 1031 and thesecond microlens unit 1041 herein, are disposed corresponding to thecollimator hole 1021 of thecollimator 102, and are different from thelens structure 053 in the prior art shown inFIG. 4 . In comparison with thelens structure 053 for implementing reverse imaging through light focusing inFIG. 4 , thefirst microlens unit 1031 and thesecond microlens unit 1041 are smaller in size, and are used only to integrate light. Therefore, less impact is exerted on a thickness of theentire fingerprint apparatus 100. - To supply power and transmit a signal to the
fingerprint image sensor 101, a corresponding connection structure circuit is usually required, for example, a wire, a signal cable, or a printed circuit board. To facilitate installation and assembly, as shown inFIG. 12 , thefingerprint apparatus 100 further includes aflexible circuit board 105 configured to transmit a current and a signal. Thefingerprint image sensor 101 is fastened on theflexible circuit board 105. Theflexible circuit board 105 may have a relatively large deformation rate, to facilitate assembly on the premise of ensuring power supply and signal transmission. - According to a second aspect, an embodiment of this application further provides an electronic device. As shown in
FIG. 13 , the electronic device includes adisplay screen 200. Thefingerprint apparatus 100 according to any one of the foregoing technical solutions is disposed at an interval below thedisplay screen 200. - As shown in
FIG. 13 , the electronic device provided in this embodiment of this application includes thedisplay screen 200. Thefingerprint apparatus 100 according to any one of the foregoing technical solutions is disposed at an interval below thedisplay screen 200, and therefore thefingerprint apparatus 100 is not attached to thedisplay screen 200. In this way, a problem that the screen is scrapped due to installation of the fingerprint apparatus through attachment to the screen can be avoided. - To prevent the
fingerprint apparatus 100 from coming into contact with thedisplay screen 200 to damage thedisplay screen 200, thefingerprint apparatus 100 and thedisplay screen 200 are usually disposed at an interval during assembly and installation. After testing and calculation, a gap between thedisplay screen 200 and thefingerprint apparatus 100 may be greater than or equal to 0.1 mm. - A corresponding installation support structure such as a middle frame is usually required for fastening the
display screen 200 and a plurality of other parts of the electronic device. Therefore, as shown inFIG. 13 , the electronic device in this embodiment of this application includes amiddle frame 300 located below thedisplay screen 200. Thefingerprint apparatus 100 may be fastened to themiddle frame 300. - To facilitate fastening of the
fingerprint apparatus 100 to themiddle frame 300, thefingerprint apparatus 100 is fastened to themiddle frame 300 through attachment and bonding. - It should be noted that in the electronic device in this embodiment of this application, for ease of description, based on a use habit of the electronic device, the
display screen 200 is usually located in an upward direction, to facilitate operation for a user. Therefore, two directions, namely, the upward direction and a downward direction, are determined. Specifically, referring toFIG. 13 andFIG. 14 , in a thickness direction of the electronic device, a direction from themiddle frame 300 to thedisplay screen 200 is the upward direction, and a direction from thedisplay screen 200 to themiddle frame 300 is the downward direction. It may be understood that thedisplay screen 200 includes a light emitting surface and a backlight surface. The light emitting surface may display an image, and the backlight surface is opposite to the light emitting surface. A side close to the backlight surface is below the display screen. - The
fingerprint apparatus 100 may be relatively thin, and therefore may be disposed above a battery region or a non-battery region of the electronic device. When thefingerprint apparatus 100 is located above the battery region of the electronic device, if a lower surface of thefingerprint apparatus 100 is lower than a lower surface of themiddle frame 300, a battery may be punctured, resulting in a serious consequence of burning the entire device. Therefore, to prevent thefingerprint apparatus 100 from puncturing the battery, referring toFIG. 13 , optionally, the lower surface of themiddle frame 300 is lower than the lower surface of thefingerprint apparatus 100. Certainly, if a process error can be ensured, the lower surface of themiddle frame 300 may be coplanar with the lower surface of thefingerprint apparatus 100. - The
fingerprint apparatus 100 and thedisplay screen 200 are disposed at an interval. In addition, during assembly of thedisplay screen 200 and themiddle frame 300, to prevent themiddle frame 300 from squeezing a display region of thedisplay screen 200, a side edge of themiddle frame 300 or another intermediate structure (for example, a plastic frame) is usually connected to a side edge of thedisplay screen 200, to fasten thedisplay screen 200. Therefore, a specific safety gap also needs to be ensured between themiddle frame 300 and the display region of thedisplay screen 200. Optionally, the gap is also greater than or equal to 0.1 mm. Thefingerprint apparatus 100 is smaller in size relative to themiddle frame 300, and is installed on themiddle frame 300, and then themiddle frame 300 is assembled with thedisplay screen 200. In this way, it is not easy to control the gap between thefingerprint apparatus 100 and thedisplay screen 200. Therefore, this can be easily implemented by using a distance between themiddle frame 300 and thedisplay screen 200 as a reference standard during installation. On this basis, as shown inFIG. 13 , provided that it is ensured that an upper surface of themiddle frame 300 is higher than an upper surface of thefingerprint apparatus 100, it can be ensured, by considering only the distance between themiddle frame 300 and thedisplay screen 200 during installation, that there is a sufficient gap between thedisplay screen 200 and each of themiddle frame 300 and the fingerprint apparatus 100.As shown inFIG. 13 , to reduce a thickness of the entire electronic device, agroove 301 is disposed downward at a position, on the upper surface of themiddle frame 300, corresponding to thefingerprint apparatus 100. Thefingerprint apparatus 100 is fastened in thegroove 301. - Assembly of a plurality of electrical elements needs to be considered in the
middle frame 300, and therefore a plurality of structures need to be considered in structure design and layout of themiddle frame 300. To facilitate manufacturing of themiddle frame 300, some installation positions are usually reserved, and then adapted installation parts are manufactured separately to install the electrical elements. For example, as shown inFIG. 13 , themiddle frame 300 includes amiddle frame body 302 and a middleframe support member 303. Thegroove 301 is disposed on the middleframe support member 303. A mountinghole 304 is disposed on themiddle frame body 302. The middleframe support member 303 is disposed in the mountinghole 304. - To prevent the middle
frame support member 303 from falling from the mountinghole 304, as shown inFIG. 13 , the mountinghole 304 is a stepped hole disposed downward along themiddle frame body 302, and an outer profile of a lower surface of the middleframe support member 303 matches the stepped hole. Fitting with the stepped hole may play a limiting role to prevent the middleframe support member 303 from falling from the mountinghole 304. - As shown in
FIG. 13 , the electronic device in this embodiment of this application includes abattery module 400 disposed below themiddle frame 300. There are abattery region 500 and anon-battery region 600 below themiddle frame 300. Thebattery module 400 is disposed in thebattery region 500. Thefingerprint apparatus 100 is located above thebattery region 500, or thefingerprint apparatus 100 is located above thenon-battery region 600, or thefingerprint apparatus 100 is located above thebattery region 500 and the non-battery region. - That the fingerprint apparatus is disposed above the
battery region 500 may be understood as follows: The fingerprint apparatus is located above the non-battery region in the thickness direction of the electronic device, and an orthographic projection of the fingerprint apparatus on themiddle frame 300 is located in a region of an orthographic projection of thebattery region 500 on themiddle frame 300. Correspondingly, that the fingerprint apparatus is disposed above thenon-battery region 600 may be understood as follows: The fingerprint apparatus is located above the non-battery region in the thickness direction of the electronic device, and an orthographic projection of the fingerprint apparatus on themiddle frame 300 is located in a region of an orthographic projection of thenon-battery region 600 on themiddle frame 300. Correspondingly, that the fingerprint apparatus is disposed above thebattery region 500 and thenon-battery region 600 may be understood as follows: The fingerprint apparatus is located above thebattery region 500 and thenon-battery region 600 in the thickness direction of the electronic device, and an orthographic projection of the fingerprint apparatus on themiddle frame 300 is located in a region of an orthographic projection of the battery region on themiddle frame 300 and a region of an orthographic projection of the non-battery region on themiddle frame 300. - As shown in
FIG. 13 , a bottom surface of thefingerprint apparatus 100 is fastened to a bottom surface of thegroove 301 through attachment. To prevent a side wall of thegroove 301 from damaging thefingerprint apparatus 100 in an installation process, there is an avoidance gap between a side wall of thefingerprint apparatus 100 and the side wall of thegroove 301. - Optionally, the avoidance gap is greater than or equal to 0.3 mm.
- The
middle frame body 302 and the middleframe support member 303 may fit with each other in a manner of using the mountinghole 304 in the foregoing solution. Certainly, there may be another manner based on a space requirement and a structural requirement. For example, a manner of slotting themiddle frame body 302 is used. In the manner of slotting themiddle frame body 302, thefingerprint apparatus 100 is located in a slot, that is, themiddle frame body 302 is not penetrated through by the slot. For themiddle frame body 302, there is a slotting manner for receiving a structure of thefingerprint apparatus 100. Specifically, themiddle frame 300 includes themiddle frame body 302 and the middleframe support member 303. Thegroove 301 is disposed on the middleframe support member 303, an assembly slot is disposed on themiddle frame body 302, and the middleframe support member 303 is disposed in the assembly slot. Optionally, themiddle frame body 302 may be punctured, and a peripheral wall of thefingerprint apparatus 100 is fastened to a side wall of a hole through attachment. When a thickness of the middle frame body is the same as a thickness of thefingerprint apparatus 100, the thickness of the electronic device may be reduced. - It should be noted that the
middle frame body 302 is usually made of an aluminum alloy material, and the middleframe support member 303 may be made of any one of an aluminum alloy material, a steel sheet, an FR4 resin material whose strength meets a requirement, or the like. - According to a third aspect, an embodiment of this application further provides a manufacturing method.
